Thanks Anwynn :) A NFT (Non-fungible token) is just data stored on a distributed ledger. They are used a lot for trading crypto currency. If you don't know what they are, then there's a good chance you don't need to worry about that restriction in my license :D
Looking forward to your next soundtrack, except today all your other soundtrack i always noticed them on my mornings, it is nice to listen to them just after waking up :)
